The eldest of the Kardashian sisters, 36 years old Kourtney Kardashian stripped off for another sizzling photo shoot snapped by photographer Brian Bowen Smith as part of his “Metallic Life” exhibition.

The photos were first taken back in October but behind the scenes footage from the shoot was shown for the first time on the latest episode of the family’s E! reality show.

Foreign media reports that despite the photos looking flawless, Kourtney admitted she felt slightly uncomfortable about her body at the start of the shoot.

“I feel like my ass disappeared when I lost weight. We need to plump it up,” Kourtney, who slimmed down after splitting from ex Scott over the summer, said.

The photographs which are printed on metallic paper and presented with no glass to emphasize the "tantalizing textures of skin", went on display at the De Re Gallery in Los Angeles between October 22 and November 19.
